Notes: n is the number of taxa used in the comparison; ROB is the observed ratio between body lengths of the largest representatives of the taxa considered in the compared territories, table 1; RTH is the theoretical ratio predicted from equation (2.2) using Q10=2.3 and the observed temperature difference ΔT between the compared territories; δ=((RTH−ROB)/RTH)×100% is the relative difference between the observed and theoretically predicted values.
